DOW Nitrogen And Phosphorus Loads

Primary ambient monitoring stations have ongoing water quality monitoring that oftentime extend for decades, making these stations ideal for studying water quality trends over time. The contributing basins are necessary to determine yields and understand land cover and uses that impact water quality. Contributing basins were derived using the StreamStats (USGS, 2017) web application . These data also include nutrient (total nitrogen and total phosphorus) loads and yields data for the basins included in the studies, Nutrient Loads and Yields in Kentucky: 2005-2017, and the Update to the 2019 Nutrient Loads and Yields in Kentucky Study, with a study period of 2005-2019.

Section 305(b) of the Clean Water Act requires states to assess the condition of the Waters of the US. The Kentucky Division of Water, in cooperation with other agencies, collects biological and water quality data to assess the condition of the resource and reports this to Congress every two years in the Integrated Report to Congress. (https://www.water.ky.gov/sw/swmonitor/305b/) These data represent the assessment results for surface waters of the Commonwealth of Kentucky.

A Total Maximum Daily Load (TMDL) Report is a water quality restoration plan that describes how pollutant loads in an impaired waterbody can be reduced to meet water quality standards. In a TMDL report, you will find the TMDL calculations establishing the allowable amount of a specific pollutant that an impaired waterbody can receive while still meeting water quality standards for each designated use. A TMDL report can contain multiple calculations and can address multiple waterbodies within a watershed.Additional information found in a TMDL report includes watershed information, the waterbody location, sampling data, pollutant sources, and strategies for meeting water quality standards. TMDL implementation plans and watershed management plans can be incorporated into TMDL reports. TMDL reports are developed by the Division of Water (DOW) and must be approved by the EPA.

Vector data set consisting of lines representing streams in Kentucky. Each line segment is attributed with the number of square miles of drainage area, and the peak flow values for 2, 5, 10, 25, 50, 100, 200, and 500 year intervals at that point on the stream. Peak flow values were calculated using the equations in the USGS Water-Resources Investigations Report 03-4180 "Estimating the Magnitude of Peak Flows for Streams in Kentucky for Selected Recurrence Intervals." The data also has attributes indicating when the peak flow values should not be used because the drainage area is out of the size range for the equation, the drainage area is greater than 10 percent impervious, or the stream segment is in a lake or pond.
